Answer 1

Here is an example of what it seems that you are asking for:

range timestamp from datetime(2022-02-01 08:06:45.7316316) to datetime(2022-03-01 08:06:45.7316316) step 1d
| extend DayOfMonth = dayofmonth(timestamp)
| extend Day = startofday(timestamp)
| extend Week_Num = case(
   DayOfMonth <=7, 1,
   DayOfMonth <=14, 2,
   DayOfMonth <=21, 3,
   DayOfMonth <=28, 4,
   5)
| extend weekend = iif((Week_Num in (2, 4) and (dayofweek(timestamp)/1d) == 6) or dayofweek(timestamp)/1d == 0, "weekend","working day") 
| project timestamp, Day, Week_Num, weekend

timestamp	Day	Week_Num	weekend
